# What is an example of decreasing friction?

## What is an example of decreasing friction?

Examples of lubricants to reduce friction: Application of oils on door hinges for easy movement. Lubricants in car engine parts. Application of grease in bicycle parts. Paints for prevention of corrosion.

### How will you decrease friction on your floors?

Reducing Friction There are several ways to reduce friction: The use of bearing surfaces that are themselves sacrificial, such as low shear materials, of which lead/copper journal bearings are an example. Replace sliding friction with rolling element friction, such as with the use of rolling element bearings.

#### What are the causes of limiting friction?

Limiting friction occurs when the moving force and the force opposing motion are equal; any addition to the moving force will cause slipping. The limiting frictional force is proportional to the normal reaction between the contacting surfaces and is independent of the area of contact.

What are the limiting friction?

Limiting friction is defined as the friction which is generated between the two static surfaces that come in contact with each other. The maximum friction that can be generated between two static surfaces in contact with each other.

What is limiting friction for Class 11?

Limiting friction is the maximum value of static friction that comes into play when a body is just at the point of sliding over the surface of another body.

## What are three ways that friction can be reduced?

Methods of reducing friction A bicycle mechanic and motor mechanic uses grease between the moving parts of these machines to reduce friction and increase efficiency. When a few drops of oil are poured on the hinges of a door, the friction is reduced and the door smoothly. We Sprinkle fine powder as dry lubricant on carrom board to reduce friction.

### How can you decrease or increase friction?

We can reduce the friction by using lubricant and increase it by making the surface rough and removing the ball bearing, lubricant, etc. Another important invention similar to the wheel is the invention of a ball bearing. It was possible to reduce the friction greatly between the surfaces by using ball bearing.

#### How can we increase and reduce friction?

Method of decreasing and increasing friction By polishing: Friction between two surfaces can be reduced by polishing them. Ball-bearing: As the rolling friction less than the sliding friction consequently in rotating machinery, the shafts are fixed on the ball bearing so that the friction can be reduced considerably.

What are different methods to reduce friction?

Polishing: If we polish a surface,it becomes smooth and friction is reduced.

• Lubricating: By applying lubricants (like oil) to surfaces,friction is reduced.
• Using ball bearings: This way of reducing friction involves the principle that an object is rolled instead of sliding.
